Program Title: DIFFERENTIAL EQUATIONS and CALCULUS version 7
DIFFERENTIAL EQUATIONS AND CALCULUS has several programs that solve
differential equations and calculus problems, and conveniently graphs them
for you on an EGA monitor. The differential equation program can solve both
ordinary and partial differential equations, find the integrating factors
of a differential equation, and create a graph of power series solutions.
The calculus program can find the derivatives of an expression in x and/or
y, graph the function of y=f(x), graph a function with its first and second
derivatives, solve and graph parametric equations, find the integral of
simple functions, and find the surface contour of the function z=f(x,y).
EULER is another differential equation program on this disk that lets you
define the function, input the step, and enter the initial and maximum
values of x and y. The program then graphs the function for you on the
screen. DIFFERENTIAL EQUATIONS AND CALCULUS is an excellent and easy to use
math program, which can be used for personal use, homework, or as an
educational tool. It includes two programs that use a math 8087 coprocessor
chip, which speeds up the program's calculations.
Usage: Differential Equations and Calculus
System Requirements: 128K memory, one floppy disk drive, and EGA color
graphics (some programs need a 8087 math chip).
How to Start: Type FILENAME (press enter), FILENAME is equal to the name of
the program that you want to load. For example, if you want to load the
CALC program, you type CALC (press enter).
Suggested Registration: $30.00
